Application filed January 20, 1923. Serial No. 613,820.

.Toallwhomitma concern:

' Be 'it known that ELLSWORTH L. LAKE, a citizen of the United States, and resident of Monroe, Monroe County, Michigan, has invented certain new and useful Improvements in Container-Making Machines and Methods, of which the following is a specification This invention relates to the manufac- 1 ture of fibre containers, such as those made I of paper or other'sheet material, and more particularly to the manufacture of round or cylindrical containers of this general character. Generally stated, the object of the inven- 1 tionis to provide a novel and efficient method of making containers from sheet material, preferably from cylinders of paper or other fibrous material, so that the containers maybe manufactured cheaply and economically and employed satisfactorily in use for various purposes. Another object is to provide a novel and improved machine for making the containers from tubes or cylindrical bodies, by passing thebody or tube automatically from one operation to another, so that each tube or 10 sired character.

It is also an object to provide certain de tails and features ofconstruction and novel combinations tending to increase the general efliciency and the desirability of a method 1 lindrical fiber containers of this particular character. i

To these and other useful ends, the invention consists in the matters hereinafter c0 setforth and claimed, and shown in the accompanying drawings, in which,-

As thus illustrated, the invention comprises a body frame 1 of any suitable character,preferably supported by legs 2, whereby the various operative elements of the machine are supported in suitably elevated positions. A longitudinal shaft 3 is su ported in bearings 4 and 5, the lower en s of these bearings being suitably attached to the body frame 1 previously mentioned. A.

. which have parallel tube carrier 6 is keyed upon said shaft in any suitable manner, said tube carrier having six equidistant tube holders 7, which are cylindrical and axes extending parallel with the shaft 3 previously mentioned. A. friction driven clutch member 8is suitably secured to one end portion of the shaft 3, and is provided with six stops 9, in proper relation to the equidistant tube holders 7 previously mentioned. The driving clutch member 10 frictionally engages the member 8 and has a spiral gear-'11 which is engaged by the spiral pinion 12 on the transverse shaft 13, the latter being suitably supported in bearings on the body frame. It will be understood that the clutch member 10 is loose on the hub portion of the member 8, so that the member 10 can rotate without rotating the shaft 3 of the tube carrier. A vertically reciprocating element 14 is adapted to be interposed in the path of the stops 9, and to be withdrawn from said path, whereby to hold the carrier 6 stationary in .each of its six positions, whereby said carrier may rotate a distance each time equal to the distance between any two consecutive tube holders 7, whereb these tube holders always stop in one of the six stationary positions of the carrier. A. cam 15 is secured to the shaft 13, and is adapted to-engage the roller 16 on the u per end of the vertically reciprocating el ter is connected by a link 18 with the lever .19, which swings up and down about its axis 20 on the body frame. The free or movable end of the lever 19 is connected by to be rotated thereby,

. fully appear.

ement 17, which lat in raised position, sov held normally stationstops 9, and the friction clutch member 10 then drives the friction clutch member 8 and rotates the shaft 3 a distance until the element 14 is released by the cam and allowed to engage another stop 9 on the clutch. In this way, ous friction drive is eration of the rotary latter does not have a employed for the 0ptube carrier, but the continuous rotation,

but to the contrary is rotated intermittently,

inasmuch as the operations to be performed on the tubes (one such tube is shown in Fig.

therefore, the continu- 28) require that the tube carrier be stationary while such operations are being performed, as will hereinafter more fully appear.j

Now the tubes are preferably fedautomatically to the rotary carrier 6, and for this purpose a vertically disposed hopper 24 1s employed to support the tubes one on top of the other so that thetubes are horizontal. At the bottom of'this hopper there is a guide 25 in which the lowermost tube slides endwise into the tube holder 7, which at such.

time is directly opposite this guide. To perform this operation, ablejlongitudin'ally of the machine, and is provided with a plunger head 27 to carrien connected to a lever 28 which ispivoted on the machine body at 29, and which operates in a manner which will hereinafter more The head 27 is secured to the end of the guide bar 30, and the latter slides in a guide 31 suitably'mounted on the.

body frame of the machine. It will be seen that the lower portion of the head 27 has a guiding portion 32 which slides in the guide 30. formed at the bottom of the guide 25 in which the tube rests so asto slide forward into the holder'7 of the carrier. Preferably, the head 27 has asp'ring-backed plate '34 to engage the end of the-tube, so that the engagement will be somewhat yielding. and will not be liable to do any harm. The shaft 'a plunger '26 is mov engage one end of the tube and push the latter end-' 'wise into the tube holder 7 of the rotary This plunger 26 has its other end- '13 previously mentioned hasits outer end provided with a=cam35 formed on its inv ner side-with a cam groove to engage-the roller 36 on the longitudinally reciprocating member 37, which latter has a slot 38 for the shaft 13, so that the member 37 reciprocates in a manner that will be readily understood. link 39 connects the pivotal away from the pivotal point 29 of the lever, .,thereby to vary or change the length of 10 stroke of the lever 28, and to thus regulate the action of the feeding means'by means of which the tubes are fed'from the hopper into the rotary tube carrier. A lever 42 is pivoted on a bracket 43, which latter is rigid and suitably supported on the body frame. This lever 42 reaches through a slot 44 in one side of the hopper for the tubes, and has an inner end portion 45 adaptedtoengage the side of the tubes, so that while the lowermost tube is sliding endwise into the rotary tube carrier, the tubes above are sup orted by the arm 42, so that the weight 0 the remaining tubes in the hopper is supported by this lever 42, instead y the lowermost tube which is thus made very free to slide endwise from the bottom of the hopper into the rotary tube carrier.

The verticallydisposed element 46 slides up and down in a stationary-guide'47 carried by the body frame, and the up er end of this element is connected by a l' 48 with the outer end of the lever 42, so that the latter is controlled in thedesired'manner. The

lower end of the element 46 has a roller or projection 49 which engages a cam groove 50 in the side of the reciprocating member 37, so that the latter in moving endwise back and forth will move the element 46 up and down and thereby control the tube engaging portion 45 in the desired manner, releasing a tube when necessary, and then promptly engaging the tube next above, so that the tube which is sliding endwise 1n the guide 25 'is never called upon to support the weight ofthe tubes above. Thus the paper tubes, such as the tube 51 shown in Fi 28,

p are automatically fed to the tube hol er 7,

so that the desired operations may be performed on the tubes, successively, to provide each tube with an end Wall, as will hereinaftermore fully appear. This point at which the tubes are fed into the carrier 6 is called the first position of the carrier, and is in a plane, it will be seen, coincident with the plane of the shaft 3 by which the carrier is rotated. i V

The member 37 is connected in any suitable ,manner with a reciprocating rack bar 52 which engages a pinion 53 on the shaft 54at the other end of the machine. This shaft 54 is mounted to oscillate in suitable bearings on the body frame, and is provided with crank arms 55,, 56 and 57, to which are connected, respectively, the pitmen 58, 59 and 60, for purposes which will hereinafter more fully appear. Looking at Fig. 16, the next position is at 61, the third position is at 62, and the fourth position is at 63, where the finished containers are 0X- pelled from the machine. For use in forming the tubes in the second position, a plunger 64 is provided, which reciprocates in a guide 65, and which is connected to the pitman 58. This plunger 64 has its front end provided with a die 66, as shown in Figs. 23 and 24, which is adapted to slide through the tube holder 7 in this second position, as shown in Fig. 24, to assist in forming the end of the tube. It will be seen that each tube holder 7 has an interior sleeve 67 provided with a shoulder 68 to limit the insertion of the tube in the holder. At the other end of the machine, the shaft 13 has a cam 69 thereon, with a groove therein for engaging the end of the rod or shank 70, which is suitably connected to the plunger 71, which is movable in a stationary guide 72 suitably supported in the body frame. The plunger 71 has a shoulder 73 which strikes the yoke 74, when the plunger is pulled backward by the cam 69, and this yoke 74 has rods 75 which slide in guides 76 and the guide member 7 2, and which have their forward ends ri idly connected toa die 77 for engaging t e edge of the tube. Consequently, when the plunger 71 is moved forward, springs 78 interposed between collars 79 and the guide 76, on the rods 75, force the rods forward, so that the die 77 is pushed forward against the edge of the tube, as shown in Fig. 24, causing the tube to be beveled or bent inward at 80, this bent portion being, of course, more or less puckered along the edge thereof. At the same time, the plunger 64 moves forward and cooperates with the die 77 to produee the effect shown in Fig. 24, and as shown in Fig. 29, and the continued movement of the plunger 71 finally brings the front end of the latter against the portion 80 of the tube, and into the cavity of the die 66, so that the formation of the end of the tube is then as shown in Fig. 25 or in Fig. 30 of the drawings. At such time, therefore, it will be seen that a flat internal flange 81 is formed in the end of the tube, and that a hollow fold 82 forms the medium of connection between this flange and the body of the tube, this fold 82 forming, as will hereinafter more fully appear, the end edge of the finished container. The co-operating dies are formed, as shown, to produce this formation of the tube, preliminary to the reception of the double thickness end wall which is preferably now inserted to form the bottom of the container.

83 is provided with a die 85 which recipro-v cates in a cutting die 86, the latter being removably mounted in a sliding yoke 87 which slides back and forth on guide rods 88 suitably supportedby cars 89 and the upright stationary frame90, which latter hasa stationary cutting die 91 detachably mounted therein. I The yoke 87 has pivoted elements 92 adapted at one end to engage the notches 93 in the plunger head 83, so that the latter and the die 86 may move forward in unison from the position shown in Fig.26, and said arms 92 also have their other ends formed to engage stationary cams 94 on the-stationary frame 90 previously mentioned. Springs 95 are provided to normally hold thearms or elements 92 against the sides of the plunger head 83, but when the front ends of the elements 92 engage the cams 94:, their rear ends are disengaged from the notches 93, so that the plunger 83 is then free to move forward alone through the die 86 and into the holder 7 and through the tube until it is in the position shown in Fig. 27.0f the drawings. A sheet of paper 96, or other suitable sheet material, is fed. downwardly in front of the cutting die 91, so that the die 86 will move forward and cut out a disk 97 of sheet materiah'and this disk will becarried forward by the die 85 and pressed against theflange 81 previously mentioned. A cam 98 has a camgroove for engaging the end of the rod 99, which latteris rigidly connected to v the plunger 100, said plunger being mounted to slide in the guide 101 and through the cutting die 102 detachably mounted in a stationary frame 103, saidv guide and frame being rigidlyconnected by bolts 104 in any suitable manner. A sheet of paper 105 is. fed downward between the die 102 and the stationary plate 106, the latter having an opening 107 through which the plunger 100 passes. The die 108 on the end ofthe plunger 100 presses the paper 105 against the edge of the cutting die 102, thus cutting out a disk 109, which is pressed by the die 108 against the outer side of the flange 81 previously mentioned. Thus the two plungers 83 and 100 co-operate to compress the two disks tightly against the flange 81 andagainst each other, and with adhesive between the two disks, a solid bottom wall is formed. It willbe seen that the disk 97 is larger than the disk 109, and that it is even a little larger than the diameter of the tube, so that, as shown more clearly in Fig. 33, the outer edge portions of the disk 97 are bent backward a distance toward the mouth of the tube, thus forming a brace or lock tending to resist displacement of the disk 97 the slide 130, which away from the flange 81 ofthe tube. It will be seen that the space 110 in the rounded fold or edge portion 82 is closed by'the edge portions of the disk 97, and that a very strong and stiff corner construction is thus provided around the base of the container. Levers 111 are pivoted at 112 on brackets 113 secured to the stationary frame 90, and these levers 111 have their outer ends pivoted at 114 on the yoke 87, so that motion of the yoke back and forth on the rods 88 is accompanied by vibration of said levers. The pitman 59 has an upstanding portion 115 adapted to engage the inner ends 116 of the levers 111, in the extremeforward move ment of the pitman 59, thereby to automatically retract the yoke 87 and its die 86 to normal position. In such normal position, the levers 111 occupy the positions shown in Fig. 15, in readiness to ward as shown in Fig. 14:, when another disk punching and applying operation is performed on the next tube.

N ow the sheets 96 and 105 of paper can be fed downward in any suitable or desired manner and by any suitable or desired means, but this is preferably done automatically. For this purpose, therefore, a slide 117 is movable up and down on the frame 90, and has pivoted thereon a member 118 provided with engaging pins 119 to engage the sheet of paper. A link 120 oonnects'the member 118 with the crank arm 121 on the rock shaft 122, and the latter is provided with a crank arm 123 connected by a pitman 124' with a crank arm \Vhen the'sha-ft122 is rocked one way, so as to pull the 1ink120 downward, the points.

crank arm 128 connected by a link 129 with is movable upward and downward on the frame 131, which is suitably mounted on' the body frame. The medium of connection between the link 129 and be again pressed for 125 on theother rock shaft 126 at the:other side-of the rotary tube carrier."

the latter being held anysuitable character. The shaft 126 has a the slide 130 is a pivoted member 132 which is pivoted at 133 on the slide, so that downward movement of the link 129 pulls the member 132 against thepaper 105, while upward movement of this link moves the memher 132 away from the paper. ".To limit the movement ofthe points 134 on the. member 132 away from the paper when the link 129 1 moves upward, which movement is only very slight in order to disengage the paper, bolts 135 have their lower ends rigidly mounted on the slide 130, and the member 132 has ears 136 with large openin s therein through which the bolts 135 pass. Vhen the link 129 moves upward, the points 134 are disengaged from the paper 105, and the ears 136 engage upward without moving the paper upward.

' To keep the paper from moving upward, a

dog 137 is arranged to engage the paper, and thus the paper can slide downward, but not upward. The rock shaft 126 is provided with acrank. arm 138connectcd by a pitinan 139 with a rotary crank 14:0 carried on the short journal l ll suitably mounted at one side of the body frame of the machine. The shaft ll is connected by gearing 142 with the shaft 13, as shown in Fig. 1, sothat rotation of the crank 140 serves to operate the rock shaft-s 122 and 126 tofeed the paper 96 and 105 downward automatically, after each punching and bottom forming operat on, and after another tube has been brought into the third position to receive the two disks to form the bottom wall.

As previously stated, the finished containers are expelled whenever a tube holder 7 reaches the position indicated at 63,.and for this purpose an automatic discharge mechanism is provided. Said mechanism comprises the crank arm 57 and the pitman 60 previously mentioned. this baror pitman 60 having a spring backed plate 143 at its other end,--said element 60 being supported to reciprocate endwise in the guide 144 supported by any suitable portion of the machine. Therefore, because of the relative timing of the di'lferent elements of the machine after each finished tube or container arrives in the fourth position of the machine. the head 143 moves through the tube holder 7 and through the tube and against-the bottom of the latter, until the head 143 is approximately in the positionshown in Fig. 2. which results in the displacement of the finished container from the. tube carrier. It will be understood,

of course, that any suitable or desired means can be employed for catching or deflecting the discharged containers. so that they will be deflected away from the operating elements of the machine, and discharged in any suitable manner.

i For driving the machine, a main shaft 145 is provided, having a pinion 146 to engage the gear wheel 147 on the end of the shaft 13, and a pulley 148 is provided on the shaft 145 to receive a driving belt.

Now it will be seen that the tube, such as thetube 51 shown in Fig. 8, is carried from the first position to the second position, from the latter to the third position, and from the latter to the fourth position, before the finished container is expelled from the machine, This being true, it might appear that-a rotary wheel or carrier having only four tube carriers would be sufficient, but in practice it is found that one having six tube carriers, as shown, has certain advanta es, inasmuch as it brings the second and third positions between the first and fourth positions, whereby there is ample clearance and room for the paper to be fed downwardly at the third postion, without interfering with the operations to be performed in any of the other three positions. Starting, therefore, with the straight tube 51, which may be a tube made by spirally winding a paper, in a well known manner, it will be seen that the first step consists in contractng one end of the tube, as best shown in Fig. 9, and that the next step consists in flattening or ironing out the puckered or gathered end portion thus formed, as shown in Fig. 30, while the final step consists in applying the paper disks to the flattened flange thus formed within one end of the tube, it being understood that the pressure is sufficient to compress the puckered or gathered paper until it isperfectly flat and thus adapted to receive the disks which form the bottom.

Now the machine is shown as being of a character to make round containers, but it will be understood that the invention is not limited to the production of containers of any particular character, although in its more specific aspects the invention is especially adapted for the making of round containers. Furthermore, it is obvious that a cap for a container may be made in the same manner, simplyby using a shorter tube, and it will be understood that the invention comprehends the manufacture .of not only the container itself, by the method and machinery shown, but also of the cylindrical cap therefor. In other words, the cap for the container will be formed from a shorter tube of slightly greater diameter, but its end wall will be formed by the application of paper disks in exactly the manner shown and described.

Of course, comparatively high speed for a machine and method of this kind is desirable, in order to reduce the cost of production, and in actual practice it is found that a machine such as shown and described may be operated at a speed sufficient to produce fifty or more containers a minute, the different operating parts being so arranged and combined that they operate smoothly and with certainty at high speed to produce the desired results.

With further reference to the construction shown in Figures 26 and 27, it will be seen that the cutting do 91 is held in place by a ring 148' and it will be seen that the inside diameter of this ring 1 18' is the same as the inside diameter of the sleeve 68, while the inside diameter of the ring 91 is, for the reasonspreviously expla ned, somewhat larger. In this way, therefore, when the inside disk 97 is cut by the dies 86 and 91, it is then pushed forward against the shoulder 149 formed by the edge 'ofthe ring 148, and the edges of the disk are bent backward a distance as previously explained, so that in effect the diameter of the disk is slightly reduced so that it may be pushed by the die 85 into the tube waiting to receive. it, as shown in Figure 27, and at such time the dies 85 and 108 co-operate to compress the two disks in the manner shown and described, and the die 85' presses the edges of the disk 97 forward to close the cavity 110 and to tighten this inner disk in the container.
